Description

TECHNICAL FIELD

[0001] The utility model relates to offshore escape cabin technical field, concretely is a gas treatment device for offshore escape cabin. BACKGROUND

[0002] In the application of offshore escape cabin, ensuring the cabin air quality is the key factor to maintain personnel life safety. The traditional offshore escape cabin gas treatment device usually adopts simple filtration and catalytic system, and its main structure includes air inlet pipeline, catalytic reaction device, basic gas circulation fan and exhaust pipeline. The traditional catalytic reaction device usually relies on the fixed temperature catalyst bed to oxidize the carbon monoxide (CO) and other harmful gases in the cabin air. However, due to the performance limitation of catalyst material, the conventional device is difficult to maintain high efficiency reaction in low temperature environment. In addition, the gas filtration part is limited to single layer coarse filter layer, which cannot effectively remove water and small particles in the gas, and the overall purification effect is not ideal.

[0003] The catalytic bed in the prior art usually works at room temperature, but the catalytic reaction efficiency is significantly reduced in low temperature environment, which cannot effectively treat carbon monoxide in the air. This makes the catalyst performance not fully utilized in low temperature conditions at sea, and the air purification effect is reduced, which seriously threatens the safety of the personnel in the cabin. The gas flow design of the conventional device is relatively simple, and a straight-through gas channel is usually used. Although this design is simple, the short residence time of the gas in the catalytic bed leads to incomplete catalytic reaction, and the harmful gases in the air cannot be completely converted. In addition, the short gas circulation path cannot ensure that each gas flow can fully pass through the catalyst bed for reaction, further reducing the purification effect.

[0004] In the existing catalytic reaction system, the catalyst bed is usually designed as a single layer, and the contact area of the gas flow through the catalytic bed is limited, and the active area of the catalyst cannot be fully utilized. This not only reduces the reaction efficiency, but also increases the energy consumption and cost of the system. In view of this, the existing problems are researched and improved, and a gas treatment device for offshore escape cabin is provided to solve the problems of low catalytic reaction efficiency, insufficient filtration effect and imperfect gas circulation, etc. The technology aims to solve the problems and improve the practical value.
